CNAME(8)CNAME(8)NAME
cname
SYNOPSIS
cname [ -3bms ] [ -v ]
DESCRIPTION
cname prompts for a passphrase and reads, from standard
input, a list of CFS encrypted file names (e.g.,
"51051f97e31613b7"). It produces, on standard output, a
corresponding list of cleartext names. By default, names
are decrypted using standard 2-key hybrid mode single-DES.
The -3 option specifies 2-key hybrid mode triple DES. -m
specifies 1-key hybrid MacGuffin. -s specifies SAFER-
SK128. The -v option includes the ciphertext names in the
output.
All names must be specified one per input line, as indi-
vidual path components (full path names are not accepted).
If a name cannot be decrypted to printable characters,
"???" is printed in its place. This is the only way to
detect an incorrect passphrase.
cname is intended to assist in making sense of CFS direc-
tories when no CFS daemon is available. It is also useful
in locating files from backups.
SEE ALSOccat(8)BUGS
Does not work with new format (1.3 and later) directories.
The program is easily confused by slightly wrong input.
It would be better if it could transparently translate the
output from other programs such as ls(1), tar(1) and
dump(8).
